Regex Editor & Tester

This regex matches a newline followed by the literal text 'description:', then any optional whitespace, and captures everything remaining in the input. The `[^]` construct is a JavaScript-specific idiom that matches any character including newlines (unlike `.`), so the capture group grabs all text to the end of the string. It's commonly used in ServiceNow to extract the description field and its full contents from raw email bodies or parsed message text.
